Effect of cavitation on high-temperature silicate melts

The effect of acoustic vibrations in the cavitation regime on high-temperature high-viscosity slag melt is evaluated experimentally.

Zusammenfassung:	The effect of acoustic vibrations in the cavitation regime on high-temperature high-viscosity slag melt is evaluated experimentally. It is determined that ultrasonic treatment greatly increases the crystallization power of melt; this could be due to depolymerization of the silicon-oxygen framework of silicate melt and the creation of an extended interface between the gaseous and liquid phases in the melt. It is shown that acoustic treatment promotes dispersion of a refractory solid phase in the melt.
